[Bug] - Can not find references for static method

[mamilic]

Can not find references for static method.

Steps To Reproduce

1. Download and open test.zip
2. Go to DemoApplication
3. Find references for public static Top of(One one), it will say no references found
   . However for method meta() in the same claas, DemoApplication, it will find references.

The error below happened on a project that I have no liberty of sharing. Hope it might be helpfull.

@mamilic - Thanks for your diligent efforts to report issues. To my knowledge most JDT committers aren't familiar with gradle or maven or such layers on top of Eclipse SDK -- Sometimes, people have expressed amazement at the lack of familiarity with maven, gradle etc - but that is how it is - we are resource constrained and a test project that shows the problem on a plain Eclipse SDK will see swifter response relatively speaking.

If I simply import the zip file, open DemoApplication.java and select Top.meta() and ask for references - I get a pop up informing me "The resource is not on the build path of a Java project" -

Tagging as help wanted - perhaps some knowledgeable person can extract a plain SDK project and attach here.
